Serial Nb.

This invention relates to valves, particularly adapted for use in drainage fittings and is a division of my pending application for Letters Patent of the United States, Serial 5 No. 387,572, filed August 22, 1929, now Patent 1,7 86,597 of December 30, 1930.

The purpose of the invention is to provide a valve movable toward or from its seat by means of a rotatable screw, the valve being m held from rotation in its opening or closing movement.

A further object and feature of the invention is to provide'a simple and inexpensively constructed valve and operating means there- 13 for including a hollow casting to which the valve is detachably secured and relative to which the rotatable screw is in threaded relation and means for holding the casting from rotation. r

A further feature and object of the invention resides in the provision with a drainage fitting of a valve operating means providing a cover for the fitting and an operating means for the valve.

These several objects and features of the construction of the invention are hereinafter more fully described and claimed, and a valve structure embodying my invention is shown in its preferred form in the accompanying drawing in which- Fig. 1 shows my improved valve construction as utilized in conjunction with a drainage fitting. I

Fig. 2 is a section taken on line 22 of Fig. 1 showing the manner of supporting the valve element from rotation while permitting longitudinal movement thereof toward or from its seat. p

This valve may be adapted for use with several types of drainage fittings only one form of which is shown in Fig. 1 and in this fitting 'a casing 1 is provided having a hub 26 for an inlet conduit in which a'swing check valve 24 and tubular element therefor is mounted to prevent back flow through the inlet conduit. The casing is provided with an outlet at the bottom having a seat 9 for a tapered valve 10. The valve is preferably of ring like form and may be secured to the til supporting element 11 in any approved man-. 7

ner as =bybeing threaded thereinto and a pin 12:inserted through the hub ofthe valve into thesupporting casting "11 which is preferably closed at its bottom endas. shown. valve supporting element 11. is preferably v The for-med of a hollow casting having. a threaded aperture..,at"the upper'end to receive the threaded stein 15 by rotation of which the element :11 may be raised or lowered .to open or close the valve relative-to its seat 9. The Q operating stem .15 is preferably supported, ina plate 4: restinglon' shoulders provided in the upper end offthe casing and a packing element 6 is provided between the plate and the shoulders The plate 4: has a hub 16 internally threaded to receive a packing nut 17 and thestem 15. extends through the packing element and ha'sa squared end 18 for ro-. tatijon thereof; The stem is further provided with'a collar '19. Wi-thinthe hub 16 supported on theplate ,wherebythe stem is held from longitudinal movement yet. permitted to be rotated. I 7 v f The preferred structure for rotating-the stem consists of a cup-shaped element 40 positioned in inverted relation in the hub end 2 of the casing and flush with the upper surface thereof- An operating lever or hand-hold 41 is pivotally mounted in anaperture at one side of the stemformed in the. upper face 30f the element-A0; Thelever 41 may be turned-upwardly, as shown by dotted lines, to provide a handle by. which the element 40' may be turned and the threaded stem 15rotated to raise or lowerthe valve. To hold the valve from rotation, the casing is providedwith the spaced lugs 14 on opposite sides will be understood from Fig. 2 providing recesses between the lugs on each side in whichradial wings 18 formed on the. element 11 are positioned and movable in avertical direction in the construction here shown or longitudinally of the stem. r V

By the arrangement'of the parts described, a drainage fitting and valve arrangement is provided that is simple in construction and the operating element provides a cover member for the upper end of the drainage fitting which is usually flush with the floor surface.

It'will be evident from the foregoing dej flush with-afloor surface, a rotatable stem which rests. upon-the plate, the said cupi scription that the various objects of the in-,

vention are attained by the construction described. H 7

Having thus briefly described my invention, what I claim and desire to'secure by 7 Letters Patentof the United States isa 1. In adrainage fitting, a chambered casing having an inlet adapted for connection with a drain and an outlet therefor, a manually operable valve controlling the outlet,"-

said casing at its upperendhaving a hub the upper end of which terminates practically for'operating the va'lve,'a plate seating in the hub in sealed relation therewith and through which the stem extends, means for sealing the interstice between the stem and the plate, said plate "and, sealing means providing a mounting for thestem preventing longitudi-' nal movement thereof, said stem terminating in asquaredend extending to practically flush with the hub, and an operating means 'for the stem comprising an inverted cup-shaped member, the lower open: end of which'rests upon the said plate-with the upper end thereof practically flush with the hub and floor surface, said upper portion of the cupped" member having a squared aperture fitting over the squared stem, and a handhol'd by means of which the cupped member andstem maybe rotated.

' 2. In a drainage fitting including a cham-j 1 bered casing having an inlet and an outlet, a valve controlling the'outlet, valve operating means including a rotatable stem extending upwardly to the top of the casing, said cas ing having an open end formed with a hub providing a shoulder below said end, a plate" secured-to theshoulder apertured to receive the valve operating stem, and operating cup-shaped member, the lower open end of shaped member engaging the end of the ro- I tatable stem,'anda handle element pivotally connected with'the said cup-shapedmember adjacent its periphery and turnable to nonoperative position practically flush with the uppersurface of the cup-shaped member and by means of which the stem and member may be rotated.
